"This zero-index metamaterial offers a solution for the confinement of electromagnetic energy in different waveguide configurations
This week in the journal Applied Physics Letters("Metamaterial electromagnetic energy harvester with near unity efficiency"),researchers from the University of Waterloo in Canada report a novel design for electromagnetic energy harvesting based on
In our group, we're trying to help solve the energy crisis by improving the efficiency of electromagnetic energy-harvesting systems."
and harvesting electromagnetic energy, classical dipole patch antennas have been used.""Now, our technology introduces'metasurfaces'that are much better energy collectors than classical antennas,
The key significance of the researchers'work is that it demonstrates for the first time that it's possible to collect essentially all of the electromagnetic energy that falls onto a surface."
"Conventional antennas can channel electromagnetic energy to a load --but at much lower energy absorption efficiency levels,"said Ramahi."
--whether it's wind, hydro, solar or electromagnetic energy.""Other key applications include"wireless power transfer--directly adaptable to power remote devices such as RFID devices and tags or even remote devices in general,"Ramahi noted.
